Apparatus and methods for correcting nasal valve collapse
The present invention relates to apparatus ad methods for correcting nasal valve collapse comprising a device configured for suspending a nasal valve, the device comprising a body portion comprising a proximal end, a distal end, and a plurality of barbs, wherein the body portion is configured to be inserted through or underneath the upper lateral cartilage of a patient and wherein the plurality of barbs are configured to engage a soft tissue overlying a bony tissue proximal to the upper lateral cartilage, and a head portion coupled to the proximal end of the body portion wherein the head portion is configured to engage the upper lateral cartilage of the patient when the plurality of barbs are engaged with the soft tissue overlying the bony tissue proximal to the upper lateral cartilage.
1. A method of supporting an upper lateral cartilage in a nose of a patient, the method comprising:
forming an aperture in tissue of a nose;
inserting a nasal implant into the aperture, wherein the nasal implant comprises a body portion and a head portion, wherein the body portion comprise a proximal end and a distal end, wherein the head portion is at the proximal end of the body portion, wherein the body portion comprises a plurality of barbs, wherein the body portion of the nasal implant is inserted through the aperture prior to the head portion;
advancing the nasal implant through the aperture to a position at which the nasal implant is over a maxilla bone within the nose of the patient;
while the nasal implant is at the position over the maxilla bone, engaging the plurality of barbs with a periosteum of the patient to maintain the nasal implant in the position; and
applying, using the nasal implant in the position, a force to the upper lateral cartilage to support the upper lateral cartilage in the nose and resist collapse of the upper lateral cartilage during inhalation.
2. The method of claim 1 , wherein engaging the plurality of barbs with the periosteum comprises applying pressure to an epidermis above the nasal implant.
3. The method of claim 2 , further comprising releasing the pressure applied to the epidermis above the nasal implant.
4. The method of claim 1 , wherein advancing the nasal implant through the aperture to the position comprises inserting the body portion of the nasal implant under the upper lateral cartilage.
5. The method of claim 1 , wherein advancing the nasal implant through the aperture to the position comprises inserting the body portion of the nasal implant through the upper lateral cartilage.
6. The method of claim 1 , wherein inserting the nasal implant into the aperture comprises using a guiding needle sheath to insert the nasal implant into the aperture.
7. The method of claim 1 , wherein advancing the nasal implant through the aperture to the position comprises advancing the head portion through the aperture.
8. The method of claim 7 , wherein, in the position at which the nasal implant is over the maxilla bone, the head portion engages the upper lateral cartilage.
9. The method of claim 1 , wherein the nasal implant is formed from a bioabsorbable material.
10. The method of claim 9 , further comprising, while the nasal implant is in the position, degrading the nasal implant over time.
11. The method of claim 1 , wherein the nasal implant is formed from a non-bioabsorbable material.
12. The method of claim 1 , wherein the body portion is 0.5 centimeters (cm) to 3.0 cm in length.
13. The method of claim 12 , wherein the head portion is approximately 0.5 centimeters in length.
14. The method of claim 1 , wherein the plurality of barbs are directed toward the proximal end of the body portion.
15. The method of claim 1 , wherein the head portion has a straight shape.
16. The method of claim 1 , wherein the head portion has a curved shape.
17. The method of claim 1 , wherein the plurality of barbs are disposed on only one side of the body portion.
18. The method of claim 1 , wherein the aperture is in a mucosa of the nose.
19. The method of claim 1 , wherein forming the aperture comprises forming a slit in the tissue.
20. The method of claim 1 , wherein advancing the nasal implant to the position comprises using an endoscope.
